Abstract

• The ankle is a complex weight-bearing joint and play an important role biomechanically. The injuries to the ankle joint compex include not only injuries that cause disruption of the bony architecture of the ankle joint but often significant ligamentous and soft tissue components. There is many study for ankle to exact diagnosis and treatment in order to anatomical reduction and stability.
  The auther analysed 105 cases(102 patients) of ankle fracture which were admitted and treated in Orthopedic Department Chungnam National University Hospital from September 1985 to February 1990. The follwing results were obtained.
  1. According to classification, the most common fracture type was suplnaton-external rotation type(33%) in Lauge-Hansen., type B (46%) in Dams-Weber, type II unstable (50%) in Tile.
  2. Among the three fracture classification, Lauge-Ransen classification is cumbersome and difficult to apply clinically because of complexity and variable fracture patterns but useful for hidden ligament injury. Dams-Weber classification is simple and easily appllcated but not helpful for decision of the treatment methods.
  3. According to Tile classification, bony avulsion fracture suggested posterior syndesmotic ligament complex inju.y was noted 26 cases (50%) in type II unstable with operative treatment.
  4. Poor cases on clinical result were due to no achieving anatomical reduction and severe initial injury regardless of operative or conservative management.
